The currency in England in 1700?

The currency of the Kingdom of England in 1700 was the Pound Sterling - exactly the same currency as the UK has now.

Well, not quite the same. Today's pound has decimal sub-units. Before that, there were many different non-decimal fractions of a pound as well as there being the guinea (a gold coin worth 1.05 pound), which had its own array of sub-units. Also, there was no pound coin. The largest in that era was only 1/4 of a pound
